  1. Hi @catphish, I took a look at the possible build list for the Arty S7 and it seems that the Piecemaker board is a build option for the two versions of the Arty S7, which I was surprised to learn. The datasheet that I am looking at the for the Piecemaker DDR chip (link to datasheet) seems to say in some places that it will work with either voltage (such as in the description on page 4 and page 11) but the list of the parts list on page 5 seems to say only one particular part works on 1.35V. However, we have one of these Arty S7 boards with that same PMF511816EBR-KADN chip and we verified that it works correctly and measured the capacitors that it runs at 1.35V. I have reached out to our design engineer for this board to confirm this though. Thank you, JColvin
  2. Hi @RedMercury, I learned that those distances do not include the leg distances, so they just go to the through hole. Based on the datasheet for the female Pmod header you should be able to find out those details if you want to though. Thanks, JColvin
  3. Hi @RedMercury, I have reached back out to our layout engineer to find out this detail for you. Thanks, JColvin
  4. Hi @spri, I have moved your question to a more appropriate section of the forum where the engineer much more familiar with WaveForms SDK will be able to see and respond to your question. Thanks, JColvin
  5. @zygot no problem, I'm glad I could help out. For others reference (just in case there are other situations where the pdf displays differently than the two situations mentioned on this thread), this is what I see on page 3 of the schematic in my Firefox browser on my Windows 10 machine: Thanks, JColvin
  6. Hi @zwilcox, We weren't readily able to update the Zybo Base System Design to a newer version of Vivado. We do have an unofficial version of a Zybo Base Linux Design for our Petalinux Projects here as well as a Zybo Petalinux BSP Project for Vivado 2017.4 here. Thanks, JColvin
  7. Hi @zwilcox, Unfortunately, we do not have an updated Zybo Base System Design. We are looking into updating this, though since it was originally created in Vivado 2013.4, I do not know how successful this will be. Thanks, JColvin
  8. Hi @zygot, So I can ensure the correct schematics are available, which current schematic are you referring to that doesn't have these details? The current version that I am aware of (Rev B on it's Resource Center) shows all of these details on the 3rd page. Or am I misinterpreting what you are saying? @eric_holtzclaw, to confirm, yes changing out the clock chip will cause the USB interface to break. There is a location where you can provide an external oscillator on IC4 (intended to be 100 MHz), though you would need to remove R80 so that it and the USB clock aren't interfering. Otherwise you can always using the clocking wizard to create a PLL to create your 32 MHz signal if you don't strictly need an external source. Thanks, JColvin
  9. Hi @tmwhitt, What voltage range are you applying the inputs on the Pmod AD1? Thank you, JColvin
  10. Hello, For those reading this thread, I have sent a PM with instructions on how to reprogram the JTAG SMT2's. Thanks, JColvin
  11. Hi @SeanS, Thanks for sharing what you found to solve the problem you were running into! Thanks, JColvin
  12. Hi @NikosFotias, I heard back from our design engineer about this; the recommend input ranges are 0V to 5V, but the absolute maximum ratings for the PWM inputs are -58V to 58V. Thank you, JColvin
  13. Hi @Musko, You would receive better support for this question by posting on the National Instruments forum, https://forums.ni.com/t5/Discussion-Forums/ct-p/discussion-forums?profile.language=en; the staff here on the Digilent forum are really only familiar with the LINX add-on for LabVIEW and the LabVIEW 2014 Home Edition. I'm sorry I could not be of more help. Thank you, JColvin
  14. Hi @edge30, I have reached out to some of the other engineers more familiar with embedded Linux about your questions. Thank you, JColvin
  15. Hi @mossygreen, My understanding (I don't have a Mac to confirm this) is that you should be able to click on the Apple icon on your screen and then select the Software Update option. Otherwise, I would get the FTDI drivers (what the OpenLogger uses to communicate) directly from the FTDI website here; you might need to uninstall the existing drivers first to help facilitate this. Let me know if you have any questions about this. Thanks, JColvin
